 */

/**
 * Retrieves an option value based on an option name.
 *
 * If the option does not exist, and a default value is not provided,
 * boolean false is returned. This could be used to check whether you need
 * to initialize an option during installation of a plugin, however that
 * can be done better by using add_option() which will not overwrite
 * existing options.
 *
 * Not initializing an option and using boolean `false` as a return value
 * is a bad practice as it triggers an additional database query.
 *
 * The type of the returned value can be different from the type that was passed
 * when saving or updating the option. If the option value was serialized,
 * then it will be unserialized when it is returned. In this case the type will
 * be the same. For example, storing a non-scalar value like an array will
 * return the same array.
 *
 * In most cases non-string scalar and null values will be converted and returned
 * as string equivalents.
 *
 * Exceptions:
 *
 * 1. When the option has not been saved in the database, the `$default_value` value
 *    is returned if provided. If not, boolean `false` is returned.
 * 2. When one of the Options API filters is used: {@see 'pre_option_$option'},
 *    {@see 'default_option_$option'}, or {@see 'option_$option'}, the returned
 *    value may not match the expected type.
 * 3. When the option has just been saved in the database, and get_option()
 *    is used right after, non-string scalar and null values are not converted to
 *    string equivalents and the original type is returned.
 *
 * Examples:
 *
 * When adding options like this: `add_option( 'my_option_name', 'value' )`
 * and then retrieving them with `get_option( 'my_option_name' )`, the returned
 * values will be:
 *
 *   - `false` returns `string(0) ""`
 *   - `true`  returns `string(1) "1"`
 *   - `0`     returns `string(1) "0"`
 *   - `1`     returns `string(1) "1"`
 *   - `'0'`   returns `string(1) "0"`
 *   - `'1'`   returns `string(1) "1"`
 *   - `null`  returns `string(0) ""`
 *
 * When adding options with non-scalar values like
 * `add_option( 'my_array', array( false, 'str', null ) )`, the returned value
 * will be identical to the original as it is serialized before saving
 * it in the database:
 *
 *     array(3) {
 *         [0] => bool(false)
 *         [1] => string(3) "str"
 *         [2] => NULL
 *     }
 *
 * @since 1.5.0
 *
 * @global wpdb $wpdb WordPress database abstraction object.
 *
 * @param string $option        Name of the option to retrieve. Expected to not be SQL-escaped.
 * @param mixed  $default_value Optional. Default value to return if the option does not exist.
 * @return mixed Value of the option. A value of any type may be returned, including
 *               scalar (string, boolean, float, integer), null, array, object.
 *               Scalar and null values will be returned as strings as long as they originate
 *               from a database stored option value. If there is no option in the database,
 *               boolean `false` is returned.
